    Default Compilation error with MSVC: Wrong MOC version

    Trying to compile moc_*.cpp files fails with MSVC 2005, gives error:

    This file was generated using the moc from 4.4.3. It
    cannot be used with the include files from this version of Qt.
    (The moc has changed too much.)

    Well, I just don't have and never had anything else but 4.5.1 installed on this machine. Calling
    'moc -v' gives 4.5.1 and the moc_*.cpp have preprocessor commands

    #error "This file was generated using the moc from 4.5.1. It"
    #error "cannot be used with the include files from this version of Qt."
    #error "(The moc has changed too much.)"

    So how in the world can I get errors about 4.4.3? How do I go about it? Calling 'nmake mocclean' and 'nmake clean' doesn't help.

    delete all the moc_xxxx.cpp files.

    Calling 'nmake mocclean' does exactly this. The build directory is totally empty. It still gives the same error.

    search for moc.exe and qmake.exe in your computer.. it is a possiblity that some unfriendly human has touched your pc.
